More intelligence, integration and miniaturization are demanded along with lower power consumption to maximize battery life. Researchers, designers and developers pursuing the innovations and breakthroughs needed to develop these next-generation devices typically require basic equipment such as power supplies and sources for this work. Therefore, the power supplies and sources used by these innovators also need to possess features advanced enough to meet the dificult measurement challenges they often face. The Keysight Technologies, Inc. B2900A series of precision instruments includes two next generation of power supply/source solutions that meet these needs: the B2961A 6.5 Digit Low Noise Power Source 1ch and the B2962A 6.5 Digit Low Noise Power Source 2ch. These products achieve best in class precision, support wide bipolar output ranges and have an extremely low noise loor. They also possess graphing capability and other advanced features. This makes them ideal companion products for other instruments such as oscilloscopes, network analyzers, spectrum analyzers, frequency counters, digital multi meters, nanovoltmeters, etc. - The world's only 6.5 digit resolution power source with a bipolar sourcing range from 100 nV to 210 V and 10 fA to 3 A (DC)/10.5 A (pulsed). - Optional ultra-low noise ilters can reveal your device's true characteristics with low noise performance (10 Vrms from 10 Hz to 20 MHz, 1 nVrms/ @10 kHz). - Supports both pre-deined and user-deined arbitrary waveform generation (1 mHz to 10 kHz) - Output voltage and current can be veriied quickly using the built-in 4.5 digit voltage/current monitor - Output voltage and current can be checked graphically on the B2900A's 4.3" LCD front panel display using the time-domain voltage/current waveform viewer. - Programmable output resistance feature enables the emulation of a wide variety of DC voltage and current characteristics, such as driver ICs, regulators, energy generating devices, etc. - Free application software for easy PC-based instrument control - LXI Core conformant, USB 2.0, GPIB, LAN and digital I/O interface A revolutionary power supply for precision low noise voltage/current sourcing featuring 6.5 digit, 100 nV/10 fA resolution, 10 Vrms noise, bipolar 210 V/3 A (10.5 A pulse) range, innovative sourcing functions, and GUI 03 | Keysight | B2961/62A 6.5 Digit Low Noise Power Source - Data Sheet The world's only 6.5 digit source with a bipolar range of 100 nV to 210 V and 10 fA to 10.5 A The Keysight B2961A/B2962A Power Source has broad voltage (up to 210 V) and current (up to 3 A DC and10.5 A pulsed) sourcing ranges and excellent 6.5 digit resolution (minimum 100 nV/10fA program resolution). Unlike a typical power supply/source, it supports 4-quardant operation that gives you the freedom to accurately and precisely supply any voltage or current contained within its ranges regardless of polarity. Noise loor of 10 Vrms (1 nVrms / @10 kHz) outperforms even linear power supplies Low noise performance is required for the development of noise sensitive devices such as VCOs (voltage controlled oscillators), ADC/DAC, new material based components, etc. However, conventional power supplies and sources have not been able to achieve the noise level required for these applications. The Keysight B2961A/B2962A supports an optional external low noise ilter that enables ultra-low noise performance down to 10 Vrms and 1nVrms/ (at 10 kHz), providing unparalleled low noise performance in a low-cost bench-top power source. Innovative sourcing capabilities enable test and evaluation not possible with conventional power supplies and sources The Keysight B2961A/B2962A supports a number of innovative sourcing capabilities for test and evaluation that are not available on conventional power supplies and sources. For example, the Keysight B2961A/B2962A has the ability to generate not only DC signals but also pulsed, swept and arbitrary waveforms (1 mHz to 10 kHz) in both voltage and current. Its arbitrary waveform generation capability supports common waveform types such as sine, ramp, square, etc. in addition to userdeined waveforms. The Keysight B2961A/B2962A also supports an advanced programmable output resistance feature that allows you to specify either a particular output resistance or a speciic voltage versus current source characteristic. This feature is ideal for emulating a wide variety of devices (such as batteries, photovoltaic cells, sensors, transducers, etc.) that are otherwise dificult to simulate. Finally, the Keysight B2961A/B2962A has a 4.3 inch wide LCD display and all of its capabilities are accessible from its front-panel graphical user interface (GUI). The graphical display not only simpliies user-operation, but it also facilitates viewing measurement results. With the built-in 4.5 digit voltage and current monitoring capability, you can check the output voltage or current graphically by the time domain voltage/current waveform viewer. This permits quick checking and debugging of measurement results without the need for additional equipment. 4 | Keysight | B2961/62A 6.5 Digit Low Noise Power Source - Data Sheet Key Speciications of B2900A Series Number of channels DC or arbitrary Maximum voltage waveform output Maximum current Output Pulsed Maximum voltage Maximum current Maximum Power Output Polarity Source Resolution Output Capability Digit Mininimum resolution DC Pulsed Sweep DC/Pulse/List Arbitrary wave form 0.1 to 10 Hz Noise 1 10 to 20 M Hz Measurment Capability Voltage range Source/Monitor Current range Ranges Programmable Output Resistance View Mode B2961A/B2962A B2961A/B2962A with Ultra Low Noise Filter B2961A/B2962A with Low Noise Filter 1 or 2 1 or 2 1 or 2 210 V 42 V 210 V 3.03 A 105 mA 3.03 A 200 V 10.5 A 31.8 W Bipolar (4-quadrant operation) 6.5 digit 100 nV/10 fA Yes Yes Yes Yes < 5 Vpp < 1 pApp 42 V 105 mA 4.4 W Bipolar (4-quadrant operation) 6.5 digit 100 nV/10 pA Yes only voltage output only voltage output only voltage output < 5 Vpp < 1 pApp 10 Vrms 3 mVrms (1nVrms/ @ 10 kHz) 4.5 digit built-in volt- 4.5 digit built-in voltage/ current age/current monitor monitor 200 mV to 200 V 200 mV to 200 V 2 200 V 3.03 A 3 31.8 W Bipolar (4-quadrant operation) 6.5 digit 100 nV/10 pA Yes only voltage output only voltage output only voltage output < 5 Vpp < 1 pApp 350 Vrms 4.5 digit built-in voltage/ current monitor 200 mV to 200 V 10 nA to 10 A 10 A to 100 mA 10 A to 3 A Constant R Yes No No V/I emulation Yes No No Single View Yes Yes Yes Waveform Preview Yes Yes Yes Dual View Only 2ch model (B2962A) Only 2ch model (B2962A) Only 2ch model (B2962A) Graph View (time-domain voltage/current waveform viewer) Yes Yes Yes 50 F 1 mF GPIB, USB 2.0, LAN and digital I/O (LXI Core Conformant) GPIB, USB 2.0, LAN and digital I/O (LXI Core Conformant) Max Capacitive Lead Interface 1.Supplemental characteristics. 2.Maximum voltage output is limited to 42 V for 200 V range. 3.10 A pulse range is not supported. 0.01 F (normal mode) GPIB, USB 2.0, LAN and digital I/O (LXI Core Conformant) 5 | Keysight | B2961/62A 6.5 Digit Low Noise Power Source - Data Sheet Speciications Speciication conditions The source and measurement accuracy are specified under the conditions listed below. 1.

Program Memory Program memory allows you to store long strings of SCPI command lines once into the B2961A/B2962A's volatile memory and then recall those strings multiple times while the program is executing using a single SCPI command. By storing the command strings in memory, the time that would have been spent sending those same commands over a communication bus is eliminated. For tests that utilize lots of repeated code (such as subroutines), program memory can dramatically reduce test times.
